It'v'rNITIGN APPARATUS FOR COMBUSTION-ENGINES.

Application filed January 15, 1303.

r all whom it may cm more:

Be it known that l', MARTIN A. Trim, a citizen of the United States, and a resident of Vilkinsburg, in the county of Allcgheny and State of Pennsylvania, have made a. new and useful Invention in Ignition Apparatus for Combustion-Engines, of which the following is a specification.

This invent-ion relatesto internal com bustion engines and nu. re particularly to ignition apparatus for such engines.

An object of this invention is the production of a SlillpiE, accurate and efiective ignition apparatus.

A. great deal of diiiicult y has been encountered in ignition apparatus of the make and break type because of the Wearing away, the burning away, or the breaking of the sparking terminals, and a. particular object of this invention has been the production of an apparatus of this tyne in which the rials peculiarly adapted to resist the tendency to wear, burn away and break, and

at the same time which arev adapted to per form the functions required of them- A further object s the pi oducticn of an igniter mechanism which in tseli is an organizedapparatus and whi'h be applied toany internal combui tlon engine.

A further object is the production of a s lf contained operating mechanism for the make and break device which issimple in construction and which may be readily mounted on the engine cylir der.

These and other objects, some of which are perfecting of the details of the ignition mechanism. I attain in an apparatus 1llus'-' trated in the drawings which form a part of this application.

In" the drawings accompanying this application and forming a part thereof: Figure 1 is a sectional elevation of an igniter mechanism embodying my invention; Fig.1

2 is a plan view of Fig. 1; Fig. 3 is a plan view of Fig. 1, looking in the direct-ion of the arrow on Fig. 1; Fig. 4 is a side elevation of the detail shown in Fig. 1, in con nection with a fragmental section of an engine cylinder: Fig. 5 is a partial plan view of Fig. 4 6 shows in partial secton a detail of my invention; Fig. 7 is a artial section along the line AA of Fig.

l tion and is shown in connection with a plan View of the apparatus illustrated in Figs. 1 and 2; Fig. 9 is an end. elevation of the apparatus shown in Fig. 8 inconnection with a portion of an engine cylinder; Fig. 10 is an elevation of detail of my invention; and Fig. 11 is a section along the line BB of Fig. 9.

The apparatus consists of a .make and break device 12 which. employs an especially constructed cast iron sparking terininal 13, which, with a steel stationary ternnnal 1a. is mounted on a cylindrical cover portion 15 and which is actuated by means oi a self-coiitained magnetic operating. device.

Referring more particularly to Figs. 1, 2, 3, 4t and 10; the igniter mechanism proper consists of the cover portion 15, which is adapted by its design to project through a suitable opening formed in the wall 16 of a gas engine cylinder and which is securely mounted on the cylinder. A stationary terminal 14: projects through the cylindrical cover 15 into the gas engine cylinder and is surrounded with insulating bushings 17 and 18, which are located between it and the cover portion. 15. The terminal 14: consists of a steel rod which-is enlarged at its inner end to form the sparking terminal and which is threaded at its other end andprovided with a nut 19 adapted to secure the rod firmly to the cover portion 15 by drawing the terminal end of the rod tight against the bushing 18 and compressing the bushing 17. This arrangement not only holds the rod in placebut packs the joints between it and the sleeve portion and-insulates the rod from the sleeve portion. A

. Washer 20 is located between the nut 19 and the bushing 17 and is provided with an extending lug 21 to which a- Wire'. of the ignition circuit maybe secured.

A rod 22 extends through a sleeve 23 which extends through the cover portion 15 and is mounted thereon by means 'of insulating bushings 24 and 25, and a cooperating spanner nut :26. The sleeve is rovided at its inner end with an enlarged ange 27 and the bushing surrounds the sleeve and is secured in place between the shoulder formed by the flange 27 and a. shoulder formed on the cover portion 15. The bushing 24 is secured between a specially formed Washer 28 and the cover portion-15, and the provided at itseue'r er saw 261 "in the 1136i} set excrew 31 which through secured in place on aha rod ivy bifm' \T which flange awn an 0011mm 1 cave be con rim i.

Such an ening and stationery terminals and is eccomplished by so constructing the clamp arm that when his in place on the rod the arm 43 will extend at an angle of about 150 from the general of the movable tcr mine 13. The keyevey 4'2 so iocsted. on the rod that a, tine extending thro its center and the center of the rod is pure to the general of the movable terminal 13 This, together with the arrangement of the clamp arm 39 permits the clamp arm be reversed for the purpose of rem-eyeing the terminal 13.
